| Abstract: |
Improved apparatus is disclosed for removing embedded ticks. The apparatus includes a pair of locking tongs which are especially designed for grasping an embedded tick at the skin line. Thereafter, the grasped tick is removed by means of a rotary or twisting movement. The disclosure is also concerned with a novel method whereby embedded ticks may be removed safely and intact. The method preferably employs the disclosed apparatus.

I claim:
1. Locking tongs which are especially useful for removing embedded ticks from the skin of a warm blooded host comprising a pair of cooperating longitudinally extending arms arranged in a generally side-by-side relationship, the said pair of arms having first and second end portions which include first and second terminal ends respectively, the said pair of arms being joined together on the said terminal ends of their second end portions and being progressively biased away from each other as they extend toward the said terminal ends of their first end portions whereby their said first end portions and the terminal ends thereof are normally spaced apart, the normally spaced said first end portions of the pair of arms being resilient whereby upon applying force thereto by squeezing the terminal ends thereof are moved together and whereby the said terminal ends are returned to their normally spaced relationship when the said force is no longer applied, the said terminal ends of the first end portions of the pair of arms including a pair of cooperating pressure applying members which are normally spaced apart a distance sufficient to receive the exposed body of an embedded tick whereby the exposed body of an embedded tick may be inserted therebetween and securely grasped by squeezing the said first end portions of the pair of arms to thereby force the said pair of pressure applying members together into a cooperating pressure applying relationship, an elongated locking sleeve having an opening extending longitudinally therethrough and first and second terminal end portions, the locking sleeve being mounted on the said first end portions of the pair of arms, the locking sleeve being mounted whereby the said first end portions of the pair of arms extend through the said opening and the said pressure applying members are positioned outward from the said opening, the said first terminal end portion of the locking sleeve being adjacent the said pressure applying members and the said second terminal end portion of the locking sleeve being remote therefrom, the locking sleeve being slidably mounted on the said first end portions of the pair of arms whereby it is movable longitudinally therealong between first and second positions, first stop means defining the limit of movement of the locking sleeve toward the said pair of pressure applying members, the said first stop means including cooperating stop means carried by the said first terminal end portion of the locking sleeve and the said terminal ends of the first end portions of the pair of arms, the locking sleeve being rotatable on the said first end portions of the pair of arms when in the said first position, second stop means defining the limit of movement of the locking sleeve toward the said terminal ends of the second end portions of the pair of arms, the said second stop means including cooperating stop means carried by the said second terminal end portion of the locking sleeve and the first end portions of the pair of arms, the said second stop means also including means for varying the distance between the said pair of pressure applying members, the said pair of pressure applying members being normally spaced apart a maximum initial distance when the locking device is in the said first position and being moved progressively closer together as the locking sleeve is moved toward the said second position and being fully closed when the locking sleeve is fully in the said second position, the said second stop means also including means effective to retain the said pair of pressure applying members spaced apart at a desired distance varying from the maximum initial distance to the fully closed position, the said first terminal end portion of the locking sleeve having an oval cross-sectional configuration and the said second terminal end portion of the locking sleeve having a circular cross-sectional configuration, and the said maximum initial distance being variable by rotation of the locking sleeve while in the said first position whereby exposed bodies of embedded ticks of smaller and larger sizes may be positioned between the said pressure applying members and grasped therebetween upon sliding the locking sleeve toward the said second position.
